8 Claims.

This invention relates to spectacles provided with supplementarymagnifying means and is concerned more particularly with a novelspectacleconstruction which includes, as a permanent or removable part,a structure or attachment by which a magnifying effect may be obtained.The spectacles of the invention are simple in construction and theattachment, which includes magnifying lenses, is light in weight and isprolO vided with means by which those lenses may be placed and held inthe different positions ofadjustment that may be required for bestresults. The spectacles equipped with the new attachment may thus beworn with comfort and they provide a convenient magnifying means, theuse of which does not interfere in any way with the freedom of movementor action of the wearer.

The new spectacles comprise the usual frame holding main lenses andincluding a bridge and temples, and the attachment is permanently orremovably secured .to a part of the frame end, preferably, to the bridgethereof. The attachment includes a support and a pair of holders, eachcarrying a supplementary magnifying lens,

and the support is preferably extensible so that the supplementarylenses may be properly positioned lengthwise of the line of sight. Theholders are also adjustablyconnected to the support, so that they may bemoved to and from each other and thus given the correct lateralpositions, and they are provided with means by which they may bedetachably connected to the frame, preferably at the lower edges of themain lenses.

For a better understandingof the'invention, reference may be made to theaccompanying drawing in which:

Fig. 1 is a view in front elevation of a form of the spectacles of theinvention;

Fig. 2 is a plan viewof the spectacles shown in Fig. 1 with certainparts broken away; and

Figs. 3 and 4 are plan views of modified forms of the attachment.

Referring-to the drawing, the spectacles il- 5 lustra-ted comprise aframe I!) of usual construction including a bridge I! and temples i2pivoted to the remainder of the frame. The frame carries the usual mainlenses l3 which may be ground for correcting purposes, if desired.Secured to 50 the frame is a support comprising members I4 which havecurved ends l5 hooked over the bridge at the forward curves thereof. Themembers M have openings through which extends an adjustment screw l6reversely threaded at its opposite 55 ends. A knurled wheel I] is faston the screw at (c1. ss 41 its mid-point and lies between the ends ofthe members I l. Threaded on opposite ends of the screw are rods I 8which lie in axial alignment and can be moved toward and away from eachother by rotation of the wheel ll. 5 Attached to the'outer ends of therods 18 are holders 19 for supplementary lenses 20. These holders, asillustrated, are hollow and of frustoconical shape with the large endsthereof facing the main lenses E3. The supplementary lenses are 1 7 soformed that, in cooperation with the main lenses, they provide amagnifying effect. The holders are provided with rods 2| attached totheir lower surfaces and formed with offset recesses in which may bereceived the portions of 15 the frame extending along the lower edges oflenses I3. The engagement of rods 2| with the frames maintains theholders l9 in proper position relative to the frame and the rods are soshaped that they do not interfere with the adjustment of the holderstoward and away from each other by means of screw 56 and wheel IT.

The attachment illustrated in Fig. 3 includes a support made up ofmembers 22, 23. These members have overlying, slotted ends securedtogether 25 by a screw 2G passing through the slots and may be adjustedto vary the overall length of the support, as desired. The member 23carries the adjustment screw it and wheel 17, previously described, andmounted on the screw are rods l8 attached to holders I9. The member 22may be attached to the spectacle frame permanently as by having its ends25 soldered or otherwise secured to the bridge I l, or the ends may becurved to permit their being hooked over the bridge, as in theconstruction illustrated in Fig. 1. The holders I9 of the Fig. 3construction are provided. with the hooks 2! similar to those previouslydescribed.

The attachment illustrated in Fig. 4 includes a support formed of a pairof members 26, 21 having overlapping slotted ends connected by a screw23. The member 2'! carries a block 29 at its outer end having axialaligned openings extending inward from its lateral faces'or, ifpreferred, a passage 30 may be made in the block from end to endthereof. Projecting into the openings are rods 35 carrying holders 32similar to holders 1% and the rods are secured in proper relativepositions in the block by set screws 33 mounted in the block andengaging the portions of the rod lying within the openings therein. Theholders 32 are provided with appropriate supplementary lenses and havehooks 2i attached thereto. The rods 3! are preferably of non-circularcross-section, as are, also, the openings in block 29.

When the attachment is a permanent part of the spectacles, the holders[9 may be swung away from the lenses l3 about the screw It as an axis,to permit lenses l3 and 20 to be cleaned. For this purpose, the hookedrods 2|, which are of relatively flexible material, maybe sprung clearof the lower edges of the frames and the holders swung, as described.The holders may be adjusted toward and away from each other by theadjustment means provided and, in those forms of attachment whichinclude a two-part support, the holders may also be adjusted toward andaway from the main lenses. In all forms of the invention, the magnifyingattachment, when in position and properly adjusted, requires noattention and by its use the wearer is provided. with magnifying meanswhich will in no way interfere with his freedom of action. The newspectacles 'may, therefore, be used to advantage by surgeons,laboratoryworkers, and others who require magnifying means and, at thesame time, must be free to use both hands.
